However, extra-adrenal pheochromocytomas as well as non-chromaffin paragangliomas, including those of the carotid body and glomus jugulare, may produce symptoms from catecholamine secretion. One of the extra-adrenal sites from which these tumors arise is from a collection of para-aortic, (...)

  Foregut cysts are clinically classified as :
  bronchogenic cyst
  esophageal duplication cyst
  enterogastric duplication cyst
  ciliated hepatic foregut cyst.
  A foregut cyst can occurr in the retroperitoneum and can be difficult to distinguish from other retroperitoneal cystic mass lesions (retroperitoneal cysts). (...)

  pronephric
  mesonephric
  metanephric
  müllerian (paramesonephric).
  Müllerian cyst of the retroperitoneum is an extremely rare disease that is thought to be a subtype of urogenital cyst. It is a benign condition that can be cured with surgical resection.
  Müllerian cyst of the retroperitoneum occurs in women from 19 to 47 years of age.
